I'm not sure Malc4D has got it right, I will of course be gladly corrected.
If I was you I would get in contact with the IOM aircraft registry in addition to your efforts to get N reg work. Manx registry will validate FAA tickets (means you get paid).
They certainly dont want to start acting as a recruitment agency and are indeed very busy, but the DCA is a very nice chap who might know somebody who might know somebody if you get my meaning.
You stand a better chance of getting a reccomend whilst they have 40 aircraft on the register than when they are trying to look after 400! You might just get lucky but don't make a pain in the arse out of yourself - write first....
Best of Luck
